Cant open UE4 Autosave has a discriptor file error

i accedentally saved over my game with the menu portion of it and now im tying to open a auto save but as soon as i double click one or all of them they all come up with an error saying

Failed to open discriptor file C:/Users/username/Documents/UnrealProjects/ etc etc and will not open

What file are you trying to open, and how?

We only auto-save assets (.uasset) and maps (.umap), however the error you’re seeing there is about being unable to open a .uproject (or .uplugin) file.

thanks for replying so quickly i have fixed it i just put the latest autosave into my content folder so it would show up in the editor. that problem is solved…but i now have another issue i was wondering exactly where to go to disable the texture blurring when the camera moves away from an object with a material applied
